I have always locked my equipment if I was mowing where I wouldn't have the truck if sight. But, today I was mowing about 100 yards from the truck and it was in full sight. I was watching my tracks to keep a straight line and when I looked up to check the truck I saw a guy just leaving the truck. He didn't appear to be carrying anything, but I made a beeline to the truck and checked it all out. He had opened a gas can and threw the cap out into the parking lot of the church I was working on. I could tell he had opened the door, and messed with some boards I had in the open trailer. So far I have not noticed anything missing. I went back to finish and later he appeared again running down the street. He again came around the church, went behind it by the truck again, crossed the back yard and to a house next door and went inside. A good lesson for us all, lock that equipment no matter what the situation. I could not believe he was so brazen as to "check" out the truck with me in full sight of him, and that he obviously lived right next door. When I went to the front of the church I found an unopened pack of chips which he probably had stolen from the 7-11 store across the street and dropped when he was running. How stupid and brazen can he be. Or maybe I'm the stupid one for being so naive to think someone would never steal from me with me watching them. Sorry to be so long winded, but thought it may save someone the expense of replacing some equipment. Lock it up.
